Line 19:

With anything more complex than that, it probably means a higher-level structure is in order. Any <code>*</code>s or <code>&</code>s in a type apply to everything on their left. So

const char * & * const foo;

is a constant reference to a constant pointer to an array of constant characters, and

char * * const * foo;

is a pointer to a constant pointer to a pointer to a character array.

By the nature of references in C++, a constant reference would be meaningless. Creating one may result in a compile error. (References behave very much like constant pointers.)
